discard and fetch?
I like that.
What's missing is the part that they refer to front. Maybe
discardFromFront() and fetchToFront()? But then I like discardFromFront()
and appendToFront() better - the latter is about as long and more
informative.
Don't forget that these are relatively rarely used.

Actually, I don't think these functions would be relatively rarely used. I
don't see that many people using a buffered input's popFront. Instead I see
shiftFront in its place and an appendToFront call has to be made whenever
buffer.front.empty.
Why not popFront if empty? Maybe you could use appendToFront if you
knew that you needed to expand the stream's buffer, but that doesn't
sound like a common case.
Torarin
Exactly. Consider line continuations. Most of the time you read one line
at a time and everything goes swell. On occasion you'll have a line
continuation convention (line ends with a backslash, unmatched quote
etc.) and you need to expand the current buffer to gobble the next line.
